The Balkanization of the media means that nobody is having a single conversation with a single set of agreed-upon facts and assumptions the way you had as recently as the 90s.
People automatically assume and expect that every moment and every bit of personal data should be broadcasted on social media, especially as it relates to them - and thats just not cuttin' it for me. If you can make it through the age of social media and come out with the same friends and lover, kudos!
Ought we not to ask the media to agree among themselves a voluntary code of conduct, under which they would not say or show anything which could assist the terrorists' morale or their cause while the hijack lasted.
